After the first check, how often must cargo securement be re-inspected during a trip?
- Every 3 hours or 150 miles, and at each duty status change
- Every 8 hours or 500 miles, and at the end of the trip
- Only at each fuel stop and at the final destination
- Every hour or 50 miles, whichever comes first
Show the answer
A. Every 3 hours or 150 miles, and at each duty status change
The load is re-examined whenever the driver changes duty status and after 3 hours or 150 miles of driving, whichever comes first. Waiting for a fuel stop could leave the load unchecked far too long.

A driver's alcohol test shows a concentration of 0.03. What must happen?
- The driver may keep driving because the result is under 0.04
- The driver is kept off safety-sensitive work for at least 24 hours
- The driver must complete the full return-to-duty process
- The driver's CDL is disqualified for one year
Show the answer
B. The driver is kept off safety-sensitive work for at least 24 hours
A result of 0.02 or more but less than 0.04 is not a rule violation requiring a substance abuse professional, but the driver must be removed from safety-sensitive functions for at least 24 hours. Carrying on because the result is below 0.04 is the mistake.
